MB Bike the DriveThis event occurred in the past.

MB Bike the Drive is Chicago's kickoff to summer.
With Chicago recently being named the #1 bicycling city in America by Bicycling magazine, what better way to celebrate than with a ride on the city’s crown jewel roadway — Lake Shore Drive. So grab your bike, or rent one on-site, and enjoy almost 5 hours of car-free riding. Proceeds benefit Active Transportation Alliance’s work to improve biking, walking and transit throughout Chicagoland.
